Beslenme ve sağlık, birbirinden ayrılmaz bir bütündür. Ayrıca bireylerin diyete uyumu, diyetin içeriğinden daha fazla önem taşımaktadır. Aralıklı oruç, çeşitli protokollere sahip olan ve temelde komple aralıklı oruç, modifiye edilmiş aralıklı oruç, zaman kısıtlı aralıklı oruç ve Buchinger oruç periyodu olmak üzere 4 başlıkta incelenen bir diyet modelidir. Başlangıçta artan obezite prevalansına yönelik obez bireylerde vücut ağırlığı kaybı stratejisi olarak uygulanan alternatif bir diyet yöntemi olarak ortaya çıkmış olsa da aralıklı orucun, klinik öncesi ve klinik çalışmalarda çeşitli metabolik yollarla glukoz, lipid, protein metabolizmasını etkilemesinin yanı sıra sirkadiyen ritim, oksidatif stres, inflamasyon gibi faktörleri de etkileyerek diyabet, kardiyovasküler hastalıklar, nörolojik hastalıklar ve kanser gibi çeşitli hastalıklarda olumlu etkiler sağladığı ve bunun yanında aralıklı oruç protokolünü uygulayan bireylerin diyete uyumunun, günlük enerji kısıtlaması içeren diyetlere uyumu ile benzer olduğu gösterilmiştir. Bu derlemede; farklı aralıklı oruç modellerinin çeşitli hastalık durumlarında oynadığı rollerin ele alınması amacıyla güncel literatürün taranarak özetlenmesi amaçlanmıştır. Literatürdeki bilgiler ışığında, sağlıklı beslenme ilkelerinden uzaklaşmadan uygulanan aralıklı orucun, profilaktik veya terapötik olumlu etkilere sahip olabileceği düşünülebilir fakat insanlara yönelik çalışmalar, çoğunlukla fazla kilolu ve obez erişkin bireylerle yürütüldüğü için aralıklı oruç protokollerinin her yaş grubunda uygulanmasının güvenli olup olmadığı tartışmalıdır. Ayrıca literatürde, birçok aralıklı oruç protokolünün yer alması ve oruç protokollerinin standartlaştırılamamış olması önemli bir sorundur. Daha net ve kesin sonuçlar için bu konuda daha fazla çalışma yapılmasına ihtiyaç vardır.

Nutrition and health are inseparable from each other. In addition, compliance with the diet is more important than the content of the diet. Intermittent fasting is a diet model that has various protocols and is mainly examined under four headings: complete intermittent fasting, modified intermittent fasting, time-limited intermittent fasting, and Buchinger fasting period. Although it initially emerged as an alternative diet method applied as a weight loss strategy in obese individuals for increasing obesity prevalence, it affects glucose, lipid and protein metabolism through various metabolic pathways, as well as by affecting factors such as circadian rhythm, oxidative stress, inflammation in preclinical and clinical studies. It has been shown that it provides positive effects in various diseases such as diabetes, cardiovascular diseases, neurological diseases and cancer, and that the compliance of individuals who follow the intermittent fasting protocol is similar to their compliance with diets containing daily energy restriction. In this review; it is aimed to summarize the current literature by reviewing the roles of various intermittent fasting models in health and illness. In the light of the information in the literature, it can be thought that intermittent fasting applied without departing from the principles of healthy eating may have prophylactic or therapeutic positive effects, but it is controversial whether intermittent fasting is safe in all age groups since intervention studies on humans are mostly conducted with overweight and obese adults. More studies are needed on this subject for clearer and more precise results.
